We're 60 & 63, and have done the Panama Canal twice. First time on the Ocean Princess in April 2000, and just on Carnival Spirit in April of this year. Princess is the only way to go. We've done 7 cruises, and this past one on the Spirit was by far the worst. Many problems with the ship, even though it's only a year old, such as electrical, elevators, air-conditioning (the following cruise to Hawaii was cut short, and the next cancelled altogether) Treat yourself, and go on any of the Princess ships. We've done the Ocean, Sun and Dawn, and would highly recommend them to anyone. Please write a review when you return. Good luck!
